WIRE MATTRESS.

SPECIFICATION forming part of Letters Eatent No. 706,970, dated August 12,1902.

I Application led April 5, 1901l Serial No. 54,519. (No model.)

To all whom it mfc/y concern:

Be it known that I, CYRUs SING LLOYD, of Sowerby Bridge,Yorksliire, England, have invented certain Improvements in Wire Mattresses, of which the following is a specification.

This invention relates to improvements in woven-Wire mattresses; and the object of the invention is to provide means for stretching and maintaining the tension of such Lmattresses laterally or transversely, whereby sagging of the mattresses is prevented and a more tightly and evenly stretched mattress is obtained with less weight'of wire than has been possible under former constructions.

The invention consists generallyin a wovenwire mattress havingextra Wires or cables extending in diagonal directions through or partly through the mattress lengthwise thereof and connected to the end rails of the frame, so that by adjusting the rails the fabric may be stretched laterally to any length desired and maintained in its stretched condition.

The invention consists, further, in the constructions and combinations hereinafter described, and particularly pointed out in the claim. V

In the accompanying drawings, Figure 1 is a plan View of a mattress-frame with a portion of a woven-wire covering applied thereon and with my improvement arranged in connection therewith. Fig. 2 is a side elevation of the mattress-frame, showing the manner of attaching the cables or wires. Fig. 3 is a transverse section, on an enlarged scale, on liner@ a: of Fig. 1. Fig. 4 is a similar section on line y y of Fig. 1.

In the drawings, 2 represents the mattressframe, which is of usual construction and is provided with the movable end rail 3 and bolts 5, by means of which said rail may be adjusted. f

7 represents the woven-Wire fabric that is secured to the mattress-frame. At one end the fabric is turned vdown over the edge of the stationary rail-9 and is secured in place `by means of a suitable strip 11 in the usual way, and at the other end of the mattress the end of the fabric is turned down over the edge of the movable rail 3 and is secured in place by means of the strip 13. A series of wires or cables 15 are threaded through a series of the coils of the fabric, extending,pref erably, for a considerable distance parallel with the edge of the bed, as illustrated in Fig. 1. The wires or coils are then carried below the fabric and extended diagonally to the ends of the frame, to which they are secured by the samemeans that secures the fabric itself. As shown in Fig. 1, these wires `or cables are preferably threaded through a portion of the length of two or more of the usual strengthening-coils, or, if preferred, they may be passed through the singlecoils or ordinary portion of the fabric. I have shown in the drawings, for the purpose of being passed through the fabric, hollow cables, each of which is made up of a seriesof spirally-coiled wires, which are run together until they form a tubular cable. (See Figs. 3 and et.) /Vhen the mattress is stretched lengthwise in the usual way, by moving the end rail 3 the cords or 'wires 15 are likewise stretched and tend to straighten themselves, thereby putting tension on the mattress crosswise and stretching the. same laterally or outward equally throughout from the center to each side thereof to any desired extent and maintaining said fabric in its stretched condition. I preferably secure the stretching cords or wires as near the ends of the cross-rails as convenient, so that the strain is localized where the strength of the framing of the mattress is greatest, and this enables me to employ lighter framing and lighter cross-rails.

Instead of attaching the ends of the stretching cords or wires directly to the cross-rails or end pieces they may be attached to springs secured to said cross-rails or end pieces to give increased flexibility or elasticity..

Instead of employing the hollow cables arfranged as above described I may employ straight wires, although I consider the cables preferable, as they possess greater elasticity. The stretching wires or cables may, if preferred, be arranged entirely under the mattress fabric and suitably connected thereto, if preferred. I have shown and prefer to use a straight cable located at each edge of the mattress, although this may be omitted, if preferred.
